composer – Cannot enable simple fb connect module

Drupal 8.9.13.
Acquia Devdesktop on Windows

I installed Simple FB connect module via composer as directed by documentation current version and tried the dev version too: composer require “drupal/simple_fb_connect:3.x-dev”.

The module seems to be installed along with the required Facebook SDK library which is placed in the vendor directory of the project root.

When I try to enable the Simple FB connect module, I am getting the error: Facebook SDK library is not found. I tried several times, no luck.

Please help.

Find all finite dimensional simple Lie algebras satisfying certain conditions

Let $mathfrak{g}$ be a finite dimensional simple Lie algebra over $mathbb{C}$. Suppose that $mathfrak{g}$ can be generated by five nonzero elements $x,y,x’,y’,hin mathfrak{g}$, which satisfy the following relations:

$$(x,y)=h, (h,x)=2x, (h,y)=-2ytag{1}$$
$$(x’,y’)=h, (h,x’)=2x’, (h,y’)=-2y’tag{2}$$

Basically, ${x,y,h}$ and ${x’,y’,h}$ each form a $mathfrak{sl}(2)$, sharing the same CSA, and with $(x,x’)=(y,y’)=0$. We can represent the relations graphically as follows:
Graphical representation of the generators

Question: what are all possibilities of $mathfrak{g}$? My conjecture is that $mathfrak{g}$ can only be $mathfrak{sl}(2)$, with $x=lambda x’, y’=lambda y$, for some $lambdain mathbb{C}$, but I have no idea how to prove it.

(A vague idea: maybe we can first prove that there exist $fin mathrm{Aut}(mathfrak{g})$ with $f(x)=x’,f(y)=y’,f(h)=h$, and then use our knowledge of automorphisms of simple Lie algebra to restrict the possibilities of $mathfrak{g}$?)

c – a simple interrupt polling program due to AXI DMA IP

The program transfers a data array from a Zynq-7000 PS DDR to a BRAM IP (block RAM) memory in a PL part of a FPGA due to a PL AXI DMA IP. Inferring a xilinx axi dma driver (not scatter-gather mode), an interrupt controller and the vendor’s printf function the data array is carried from the DDR to the BRAM.

python – simple function f(g(x,y))

So the main problem is

def f(x,y):
  return (2*x,2*y)

def g(x,y):
  return (-x,-y)

z = g(0,1)


it’s an example. I have one function and returned two values.
And I want to print the f(g(0,1)), do you have any idea with it?

c++ – SImple pet caring game – console

I’m a beginner programmer and i’m looking for interesting projects to improve my low skills. I tried one day to improve my skills by trying to create a small game in which a user owns a cat, and has to feed it and clean it. My main aim of the game(which yet has many illogical things like the never decreasing happiness and cleanness level) was to try and keep my code as clean and presentable as possible. The game is made in 4 different files, and I will paste them all below. I will be happy if anyone could give me help on understanding where should I improve.

Lets go into the code:


#include "Cat.h"
#include "pet game.h"
#include <iostream>
using namespace std;

int main() {
    //Create the user's profile

    //Welcome messages
            << "Welcome to Unga bonga! Here you buy pets and raise them as your kids, and try to level up, in order to finish the game!"
            << endl;

    //Command execution
    do {
    } while (true);
Cat cat;
//User user;

void showHelp() {
    cout << "The commands in this game are:" << endl
            << "1. to feed your cat, type f" << endl
            << "2. to clean your cat, type c" << endl
            << "3. to check your cat's happiness, type h" << endl
            << "4. to check your cash balance, type m" << endl
            << "5. to check your level status, type l" << endl
            << "6. to display this help message, type ?" << endl
            << "7. to exit, type e" << endl
            << "8. Finally, to play this game, enjoy!" << endl;
void commandIdentify() {
    //take input
    cin >> command;
    //identify and execute
    switch (command) {
    case 'f':
    case 'c':
        case 'h':
    case '?':
    case 'e':
        cout << "That's not a command -yet (probably)" << endl;

void feedCat() {
    cout << "Time for food!!!" << endl;

void cleanCat() {
    cout << "Let's take a bath!!!" << endl;

void checkHappiness(){

int exit() {
    return 0;

pet game.h:

    #ifndef PET_GAME_H_
#define PET_GAME_H_

#include <iostream>
#include "Cat.h"
//#include "User.h"

using namespace std;

//Global variables
char command;
int exit();

void commandIdentify();
void buyNextCat();
void showHelp();
void tutorial();
void feedCat();
void cleanCat();
void checkHappiness();

//functions defined for a future use but they cause problems right now
void checkMoney();
void checkLevel();

#endif /* PET_GAME_H_ */


#include <iostream>
#include <string>
#include "Cat.h"

using namespace std;

    happiness = 1;
    cleanness = 1;

void Cat::feed(){
    cout << "Yummy!!" << endl;
    Cat::happiness = Cat::happiness + 0.2;

void Cat::clean(){
    cout << "So soupy!!" << endl;
    Cat::cleanness = Cat::cleanness + 0.2;


#ifndef CAT_H_
#define CAT_H_

#include <iostream>

using namespace std;

class Cat {
    int happiness;
    bool happy = happiness >= 0.6;

    int cleanness;
    bool isClean = cleanness >= 0.6;
    void feed();
    void clean();
    void checkHappiness() {
        cout << "Your cat's happiness is " << happiness*100 << "%" << endl;


#endif /* CAT_H_ */

it will be great if you could tell me how to improve code

performance – PostgreSQL: Simple IN vs IN values performace

We have queries with IN filters with long list of INT values

Sometimes, they running extremely slow, and I have found suggestion to use syntax

Field IN (VALUES(1465), (1478), ...

Instead of

Field IN (1465, 1478, ...

On some cases it helps, but on other it makes query running 1000+ times slower

So the issue is:

  • some queries much faster with simple IN
  • some queries much faster with IN + VALUES

Here is explain on case when it’s extremely slow:

->  HashAggregate  (cost=5.78..9.62 rows=385 width=4)
       Group Key: ""*VALUES*"".column1" 
                   ->  Values Scan on ""*VALUES*""  (cost=0.00..4.81 rows=385 width=4)" 

What is the right way to pass long INT values list to IN filter?

I am using PostgreSQL 13.1 on Ubuntu

c++ – Simple read/write lock implementation without starvation

I’ve built a read/write lock and have been testing it without encountering any problems. It was made to avoid writer starvation, but I believe it works against reader starvation as well. I’ve seen alternatives online, but was wondering if this is a solid implementation.

If you use a normal shared mutex, new read actions can still be queued, which will prevent write actions from ever being processed while there is any read action present. This will cause starvation. I used a second mutex which will be locked by the write process and prevents any new read processes to be queued. Thank you!

class unique_priority_mutex

    void lock_shared(void)
        // If there is a unique operation running, wait for it to finish.
        if( this->_is_blocked ){
            // Use a shared lock to let all shared actions through as soon as the unique action finishes.
            std::shared_lock<std::shared_mutex> l(this->_unique_mutex);

        // Allow for multiple shared actions, but no unique actions.

    void unlock_shared(void)

    void lock(void)
        // Avoid other unique actions and avoid new shared actions from being queued.

        // Redirect shared actions to the unique lock.
        this->_is_blocked = true;

        // Perform the unique lock.

    void unlock(void)
        this->_is_blocked = false;

    std::shared_mutex _shared_mutex;
    std::shared_mutex _unique_mutex;
    std::atomic<bool> _is_blocked = false;

python – how to refactor this simple but tricky input task?

I’m embarassed i spent so much time on this seemingly simple but tricky coding exercise.

The task is this: input is various numbers.

The only valid numbers are :

  • 1,2,3 ,4,5,6
  • +1, +2, … +6
  • 1.0, 2.0,… 6.0
  • any scientific notation that represent numbers 1 to 6.

if number is 1 – print “rule1” , 2- “rule2” etc.

If input number is 0 or .0 or 0.e00 it prints all 6 – “rule1, rule2,…. rule6”

  • Negative numbers should simply be printed as-is: -1 prints ‘-1’
  • any digits in scientific notation that are not in (1 .. 6) should be printed as is.
  • any char like dot is printed as-is – ‘nine’ is printed ‘nine’

Sample input:

1.0  03
20e-1 2e1 2ва . 1e-307

expected output:


Here is my code – how to refactor it , more elegant way?:

from math import modf
